Title: Coin freed meters
IPC: G07F15/02
Filed: 1934-12-07
Abstract: 448,697. Prepayment mechanism for meters. PINCHBECK, Ltd., and ALEXANDER, W., Adams Place, Georges Road, Holloway, London. Dec. 7, 1934, No. 35285. [Class 27] Coin action, multiplecoin with delivery proportionate to value of coin.-In meter prepayment mechanism for optional use with two different coins and giving proportionate delivery, a pair of quantity wheels 2, 3 are engaged and rotated together with the coin of higher denomination, and the wheel 2 only with the coin of lower denomination. The wheel 2 is secured to a shaft 1 having an eccentric 6 forming a bearing for a pinion 5 which is held against rotation with respect to the wheel 3 by means of pins 12 working in circular apertures 13 in the wheel 3. The pinion 5 meshes with internal teeth on a wheel 9 concentrically formed on a sleeve 4 connected with the quantity mechanism. When the wheel 2 only is actuated, the pinion 5 is displaced, without rotating, around the internal teeth of the wheel 9, and, being provided with fewer teeth than the wheel 9, draws the latter round with it by a fraction of the amount of the rotation of the quantity wheel 2. When both quantity wheels are actuated, a solid drive is imparted to the sleeve 4. The mechanism is applicable to the apparatus described in Specification 448,696.

Title: Improvements in automatic regulators for coke oven plants
IPC: C10J3/24
Filed: 1928-12-01
Abstract: 321,084. Shallcross, W. M. Dec. 1, 1928. Governors, arrangements of in coke oven plant.-The speed of the exhauster is regulated by a throttle valve under control of a governor directly responsive to pressure changes within the collecting-main of a bench of coke ovens, when such changes exceed predetermined limits. The valve 30 is situated in a. cross-over main 6 between the collecting main 5 and a cooler 8 adjoining the exhauster 10, and is actuated by a motor 31 controlled by a gas bell 33 connected to the main 5; light signals 35 indicate the positions of the valve.

Abstract: 819,505. Lathe-details. JEANNERET, J. L. Nov. 23, 1956 [Dec. 30, 1955], No. 35875/56. Class 83 (3). A lathe comprises a tool slide 1, moved by a screw 5 rotated by a hand wheel 3, and a collar 17 adjustably locked to the hand wheel, the collar carrying an adjustable stop 18. The stop 18 co-operates with an abutment 21 which is swung into its operative position by the operator when the slide approaches the desired position. When the hand wheel is rotated to withdraw the slide, a shoulder on the collar swings the abutment 21 into an inoperative position. The stop 18 is adjusted between cuts according to wear of the tool 8. The slide 1 may also have a stop 34 engaging a fixed abutment 16. Several collars, each having a stop, may be provided. In the latter case, the approach of a slide to its final position may be signalled by a spring-pressed plunger 35, Fig. 10, engaging an abutment 16, there being sufficient play to ensure that the plunger does not seat before the stops 18, 21 have correctly positioned the slide. The collar 17 may be attached to an intermediate sleeve, which itself can be adjusted angularly by a fine-pitch screw to compensate for tool wear.

[Also in Division B2] In the preparation of the inside surfaces of foundry receptacles 2 such as moulds, tundishes &c., particles are projected on to the surface 1 by a centrifugal blaster 11, the waste particles are sucked out by a nozzle 56 and then a coating is applied to the surface 1 by the same centrifugal blaster 11 which may also be used to air dry the said coating. Reservoirs 16, 17 contain the particles and the coating material and valves 39, 41 allow access to an air blown conduit 33, 35, 36 fed from a compressor 42. The particles may be abrasive silicaceous grains, waste or casting splinters, crushed metal turnings, grains of cast iron or silica or preferably steel balls of 5-7 mm. in diameter. The coating may include whitewash layers such as milk of lime or tar. Also the dust of the particles and worn particles may be mixed with an aqueous solution of silicates or resins to form the coating material. In the embodiment of Figs. 1-3 (Figs. 2, 3, not shown) the apparatus comprises a first carriage 9 movable on tracks 7 aligned with a mould 2 mounted on a pivotable table 3. On the carriage 9 is a second carriage 13, movable on tracks 12 at right angles to tracks 7, that carries a framework 15 on which is mounted for vertical movement a support 19 on which is mounted the centrifugal blaster 11. Behind the blaster 11 is a shield 22 that prevents particles emerging from the interior of the mould 2 as the blaster 11 is fed therethrough. Nozzle 56 sucks up the waste and a sieve 61 separates the particles from the dust, the particles being air blown by compressor 67 back to a hopper 68, the dust being similarly blown to a dust removing cyclone device (not shown). In an alternative embodiment (Figs. 4-9, not shown) a mould (79) is arranged vertically and a centrifugal blaster 11 and combined reservoir arrangement (84) are suspended from a lifting hook (91) for lowering into the mould (79). A waste extracting and separating device (77) is provided and supplies cyclones (125), (126). The blaster 11 and reservoir arrangement (84) can be lowered beneath the cyclones (125), (126) for filling the reservoirs therefrom.

The composition may be used in the production of vulcanized tire tread stock.ALSO:Carbon black used in the reinforcing of butyl rubber is treated with ozone to produce a black characterized by a volatile content of at least 1%, of which at least one third by volume is CO2, an E.M. Surface Area within the range 90 to 150 m2/g., a B.E.T. Surface Area within the range 75 to 170 m2/g. and a Structure Index not exceeding 90, the ratio of B.E.T. Surface Area to E.M. Surface Area not exceeding 1.4/1, the carbon black having been subjected in powder form to ozonation treatment to an extent such that its volatile content is increased by at least 1%.  It is preferred that the volatile content of the carbon black is at least 2%, that at least 40% of the volatile content is CO2, that the Structure Index does not exceed 85 and that the ratio of B.E.T. Surface Area to E.M. Surface Area approaches unity.  The ozonation treatment may take place by suspending powdered carbon black in controlled proportions in an ozone-containing gas stream or by passing the ozone-containing gas in contact with an agitated bed of the black. Air may be used as a carrier and diluent for the ozone. The ozonation may take place at 70 to 90 DEG  F. although temperatures up to 300 DEG  F. may be used.  The powdered black may be passed at a uniform rate through an elongated drum, which is slowly rotated and an ozone-containing air stream also passed through the drum. A concentration of from 0.4 to 6% by weight of ozone in the gas stream may be used and best results are obtained when the ratio of carbon black to ozone does not exceed 35 to 1.

IPC: D06Q1/02
Filed: 1934-12-24
Abstract: For the production of transparent pattern effects on fabrics, yarns, &c. there is used for the printing a solution of zinc chloride thickened with cellulose or a cellulose derivative; after printing, the materials are dried at a temperature as high as convenient, for example, at 100 DEG C., to effect parchmentization of the printed portions, and are then washed, centrifuged and finish dried. For the printing mass there is used an almost saturated solution of zinc chloride, and in this is dissolved pulp, linters, regenerated cellulose, cellulose acetate, etc.; solution may be effected at 15--20 DEG C., or the cellulose may be first allowed to swell at this temperature and the mass afterwards raised to up to 75 DEG C. to effect solution; formaldehyde may be added to moderate the parchmentizing effect. In examples, the materials treated are mercerized cotton muslin, viscose fabric, and silk muslin.
